How dc seem to be messing up their universe before it has already started.

Let me start the off this post by saying I am a huge dc fan who really wants it to succeed. I'm tearing into it to point out flaws and faults.

The earliest we will see green lantern is possibly justice league part 2.

For those that don't know green lantern is an integral member of the justice league. Whatever rendition, whatever green lantern, there is almost always one in there

Also whenever the justice league is depicted the founding characters that are always the same are:

Batman

Superman

Wonder Woman

Flash

Green Lantern

These five are always there.

Therfore it doesn't make sense for him to be included in part 2. What is even worse is that DC said they may introduce him firstly in Green Lantern Corps so therefore he will maybe not even be in Justice League part 2.

DC say they want to take green lantern slowly and I can understand that since they messed him up in the previous Green Lantern movie.

However this is a team movie. All that is needed with respect to Green Lantern is to show his relationship with the other characters and for him to just be is natural cocky self if the Green Lantern is hal Jordan. Then need to showcase his powers without making it look cheap or tacky.

We as fans do not require an origin story of any of the characters really in the Justice League movie as that's kind of what they're Solo Movies are meant to introduce.

This brings me onto my next point.

According to IGN: While both Jason Momoa's Aquaman and Erza Miller's The Flash will receive their own standalone films following the release of Justice League: Part One, neither will be origin stories.

I personally find this silly as many people do not actually know the origins of these heroes especially Aquaman.

Having read Geoff John's run of aqua man in the new 52 I personally find it really interesting to see the idea of John's moving Aquaman away from a joke to someone of great power. But this could not have been done as well if Aquaman'a origins were not shown. We are shown the impact of his father and also Dr shin depicted his morals. A theme really well emphasised is the loss of identity between him being a human and being atlantean. Only an origin story can depict that well.

Flash may not necessarily need an origin story because of the flash TV series. However I would say flash's origins should be different for when Barry's mother is alive as if the TV and movie universes cross over, it would be interesting to see how both flash's realise that although they are the same person, little things can dramatically change how different their lives are. Plus Grant gustin is good at playing the moments when Barry can reconnect with his mother. Although I can understand in this case dc's desire to not dwell on flash's origin.

In a wall Street journal article the producer Charles Roven revealed that both solo films pick up after the events of Justice League and continue the stories of each respective character. "While each movie stands alone, they’re all part of one long arc of storytelling," Roven explained.

This is terrible as it would mean that the movies in between justice league parts 1 and 2 would really just be setting up for part 2. This detracts from the movies as the writers would have to continuously remember that whatever happens is just to set up part 2. This can kinda keep movies settings and characters to be limited. This is kinda similar to the flash and arrow TV series which at first of their respective seasons they were really meant to set up the characters of legends of tomorrow.

This also implies there is little sense of continuation in part 2 from part 1. I would personally have expected the events to be nearly one after another such as injustice league fighting for darkseid, who shows up in part 2.

Lastly when crafting The Flash and Aquaman's big-screen debuts, Justice League and Batman v Superman: Dawn of Justice screenwriter Chris Terrio did a significant amount of background research. In fact, he went so far as to study electromagnetic physics for The Flash and deep sea biology in the Mariana trench for Aquaman.

Additionally, Terrio read a Greek historian's account of the Atlantis-Amazon war to gain further insight into Wonder Woman. "If you told me the most rigorous dramaturgical and intellectual product of my life would be superhero movies, I would have said you were crazy," he said.

In my honest opinion the best source out their is comics. My only concern about this is that what if the dc movies are trying to be too realistic and the producers may forget partially what fans love about the comics, which isn't realistic.
